WhatsApp Malware SORVEPOTEL Spreads via Phishing Messages
A new malware strain called SORVEPOTEL is targeting WhatsApp users through phishing messages. This malware is notable for its ability to self-replicate by sending malicious messages to the contacts of infected users. The campaign has been active since at least July 2023 and has been observed in various countries, including Germany, Spain, and the United Kingdom.
How the Attack Works
The attack begins with a phishing message sent to WhatsApp users. The message contains a link to a malicious website that mimics a legitimate WhatsApp login page. When a user clicks on the link and enters their credentials, the malware gains access to their account. Once inside, the malware automatically sends similar phishing messages to all of the user’s contacts, spreading the infection rapidly.
Technical Details
The malware uses a combination of social engineering and technical exploits to infect users. The phishing messages are crafted to appear legitimate, often using the name of a contact and referencing a shared document or image. The malicious website used in the attack is designed to look like the official WhatsApp login page, making it difficult for users to distinguish between the real and fake sites.
Once the malware gains access to a user’s account, it uses the WhatsApp Web API to send messages automatically. The messages contain a link to the malicious website, which is used to infect the user’s contacts. The malware also collects data from the infected account, including contact information and message history, which can be used for further attacks.
Protection Measures
To protect against this type of attack, users should be cautious when receiving unsolicited messages, even if they appear to come from a trusted contact. It is important to verify the authenticity of any links before clicking on them. Users should also enable two-factor authentication on their WhatsApp accounts to add an extra layer of security.
WhatsApp has been working to address the issue and has implemented measures to detect and block malicious messages. However, users should remain vigilant and report any suspicious activity to WhatsApp’s support team.
Conclusion
The SORVEPOTEL malware campaign highlights the ongoing threat of phishing attacks and the importance of user awareness in preventing infections. By understanding how these attacks work and taking appropriate precautions, users can protect themselves and their contacts from falling victim to malware.
